The Study and Characterization of a Novel Structure of 1,3,5-Benzenetricarboxylic Acid

Abstract

A novel ten-interpenetrating structure of 1,3,5-benzenetricarboxylic acid was grown under solvothemal condition after heated it 16 hours. It was characterized by FT-IR, HNMR, X-ray diffraction, HRTEM. HRTEM obtain the relevant information of structural morphologies. The result of HRTEM showsed this material owned special lamella structure. X-ray diffraction showed the crystal of the new structure is of monoclinic system, space groupP1 with a=26.5039(17), b=16.4121(17),c=26.550(2)Å,α=90.00, β=91.533(2), γ=90.00, V=11544.4(17)Å3, Z=8, Dc=1.451g/cm3,μ=0.126mm-1,F(000)=5184, R=0.0891 and w (R)=0.1819 for 11318 observed reflection with I>2(I),hydrogen bond contributed to the stability of the structure. The fluorescence spectra indicated that the title compound had two stronger emission peak at 346nm and 400nm. Keywords:1, 3, 5-benzenetricarboxylic acid; novel structure; ten-interpenetrating
